You're really making me want to get it. How is it for the interior? Does it drone any of the plastics and make them rattle? That is the biggest issue with exhausts for me. I assume, however, this being a factory exhuast, it should be near-perfect.

It is near perfect! You can hear it but certainly no drone or something! BMW did a hell of a job! The sound makes you wanna drive the car even more! It is just a complete other car! And if you want peace, you just close the windows...

This is my #1 mod i ever did! And i'm not 20 anymore... (not that old )
